• If you configure only two bands in the WLAN configuration, the AP operates in the 4x4 mode on
both the data radios.
• If you configure three bands in the WLAN configuration, then all three data radios are active. The
AP operates in the 2x2 mode on 2.4 GHz, 4×4 mode on 5 GHz, and 2x2 mode on 6 GHz.
• If you enable dual 5 GHz, then all three data radios are active. The AP operates in the 2x2 mode
on 2.4 GHz, 4×4 mode on 5 GHz, and 2×2 mode on 6 GHz.
• The dedicated scanning radio and BLE are always active regardless of power.
To provide full wireless functionality, the AP45 requests 29.3 W.
You can use any of the following options to power on an AP45:
• Power over Ethernet plus (PoE+) from an Ethernet switch
We recommend that you use an Ethernet cable with a maximum length of 100 m to connect the
access point (AP) to the switch port.
If you use an Ethernet cable that is longer than 100 m by placing an Ethernet PoE+ extender in the
path, the AP might power up, but the Ethernet link does not transmit data across such a long cable.
You might see the status LED blink yellow twice. This LED behavior indicates that the AP is unable to
receive data from the switch.
